AC replacement and installation in Tucson

Every HVAC company says they do good work. We put it in writing: Tucson's only true 1-year money-back guarantee, on qualified residential installs. Most installers don't offer one. The few that do keep the decision for themselves. Ours: three tries, then your money back — interest included. It's on your proposal before you sign. Read the terms word for word.

A new AC system is one of the biggest purchases you'll make for your home, and an oversized or undersized unit costs you comfort and money for as long as you own it. Every installation starts with a real load calculation, not a guess based on your old unit's size.

Got a written AC replacement quote and want a second opinion before you sign? Text us a photo of it, or hand it to us at your free in-home estimate. We go through it with you line by line: what size system it quotes and how that size was chosen, whether the price includes a load calculation, duct testing, the parts around the unit and a quality-control visit, and who comes back if something fails. If you want our number too, we measure the house and put our price in writing, so you can compare the two side by side.

Sometimes the second opinion is a repair. A Marana homeowner called us for a second opinion on an AC that kept freezing up. We found a refrigerant leak in the indoor coil and replaced the evaporator coil. If a repair makes more sense than a new system, we say so.

A quality AC installation in the Tucson area starts around $10,500 for a 2- or 3-ton system and around $11,000 for a 4-ton system, whatever brand of equipment goes in. That is a starting price, not a quote — your home, your ductwork and the efficiency tier you choose move the number from there, and your real price is written down after we measure, never guessed over the phone.

Here is what is inside that price:

• A load calculation and a designed system, not a guess off the size of your old unit
• A pre-measure visit before installation day
• The install crew who does the work
• A quality-control visit after the system is running
• The parts around the unit: thermostat, pad, surge protector, disconnect, electrical whip, secondary safety switch, a high-rise pan when the install calls for one, and duct transitions into your existing ductwork
• Taxes
• A written warranty, so we can come back if something fails
• A maintenance plan
• The written money-back guarantee on qualifying residential installations

A much lower installed price does not cover that same list. At $7,000 to $8,000 for a ducted system, the number covers the equipment and the labor to set it. The load calculation, the pre-measure, the code work, the written warranty and the quality-control visit afterward are not in it, and they are still work that has to be done. A ductless mini-split is the exception — that is a smaller job, and $7,000 to $8,000 installed can be a complete installation, backed by our written warranty. None of this shows on install day. It shows the first time something fails, or the day you sell the house and the home inspector goes through the system. So before you sign anything, ask six questions: who actually installs it, is it sized for this house, is it to code, is it safe, will it pass a home inspection when you sell, and who comes back if it fails. Our answers are on our workmanship standards page, the repair and service warranty page and the 1-year money-back guarantee page, and the long version is in our guide, How Much Does a New AC Cost in Tucson?.

Every one of these was measured first, priced in writing, and checked again on a separate quality-control visit. Each story has the real photos from the job.

• Oro Valley, September 2026: a 3.5-ton AC and a two-stage gas furnace replaced together, with a new return duct, a float switch and an emergency drain pan under the attic equipment.
• Northwest Tucson, July 2026: a rooftop package unit replaced, with the new 4-ton unit lifted in by crane, new duct transitions built on site, and the curb sealed and coated to match the roof.
• Marana, October 2026: a 2-ton ductless heat pump installed in a garage, with the line set run in a cover up the outside wall.

Northwest Tucson is home. We replace AC systems in Marana, Oro Valley, Picture Rocks, Casas Adobes, Catalina Foothills and across Tucson.

Pick your system, answer a few quick questions, and get a real Good/Better/Best range — about a minute, no phone number required. Then we come out and verify everything in person: sizing, electrical, ductwork, the works. Not to rework the deal at your kitchen table — because our Risk-Free Systems carry a one-year money-back guarantee, and we don't put that in writing on a system we haven't measured ourselves.

None of the steps above are visible on a finished install, which makes them easy to skip — cutting them saves hours on install day, and the problems can show up years later as someone else's service call.

When researchers checked the refrigerant charge on 311 newly installed systems in a DOE-funded study, 23% were seriously over- or undercharged. Our AC installation guide covers that research and the readings to ask any installer for.

Every Picture Rocks installation includes all five, plus the measureQuick verification and photos to prove it. No guessing, we're testing.
